Abstract
The utility model discloses a level inductor which comprises a floater shell, at least one liquid inlet hole is penetrated and formed in the lower end of the floater shell wall, and a floater with a cavity is held in the cavity of the liquid inlet hole, wherein, a first inductor is fixed at the upper end of the cavity of the floater, and a containing pipe is sleeved at the upper end of the floater shell. A second inductor is arranged at the upper end surface where the lower end of the containing pipe clings to the floater shell, and the second inductor is connected with a signal output wire. Because the floater of the level inductor is arranged in the floater shell, the level inductor is enabled to be suitable for the unquiet liquid level environment. Furthermore, the cavity wall surface of the floater shell lengthways forms a plurality of positioning bars, and a lug boss is formed on the top of the floater. When the level inductor is applied to the ropy liquid environment, the positioning bars and the lug boss can effectively prevent the floater from gluing the cavity wall surface of the floater shell, thus the condition that the level inductor can not accurately detect the level is avoided.
Description
[technical field]
The utility model relates to a kind of switch of the change operation by physical state, refers in particular to a kind of liquid level sensor.
[background technology]
Level sensor is installed usually, with the level condition of the employed liquid of detection machine equipment on the machinery and equipment such as the PCB machine.The float of common level sensor is fully outer naked setting, any other parts promptly are not set around float, when it was applied to the liquid of liquid level upheaval, the relief intensity that float produced was bigger, so that level sensor fails to detect exactly the level condition of liquid.
[summary of the invention]
The purpose of this utility model is to overcome the existing shortcoming of common level sensor, and a kind of level sensor that is applicable to wavy liquid level and viscous solution is provided.
The purpose of this utility model is achieved in that a kind of level sensor, include a float shell, the lower end of the shell wall of described float shell runs through and is formed with at least one inlet opening, contain a float with cavity in its inner chamber, the upper end of the cavity of described float is fixed with one first inductor, the upper end of described float shell is arranged with a containing tube, the upper end surface that described float shell is close in described containing tube lower end is provided with one second inductor, and described second inductor connects output line.
In the above-mentioned level sensor, the inner chamber wall of described float shell vertically is formed with a plurality of positioning bars.
In the above-mentioned level sensor, the end face of described float is formed with a boss.
In the above-mentioned level sensor, described second sensor is provided with by a centring ring.
In the above-mentioned level sensor, be arranged with a mounting flange on the described containing tube.
Than common level sensor, the beneficial effects of the utility model are: float is arranged among the float shell, at the liquid level of float housing exterior comparatively under the situation of upheaval, the inside liquid level of float shell can keep relatively placidity, helps the level sensor level condition of tracer liquid exactly; The inner chamber wall of float shell vertically is formed with a plurality of positioning bars, and the end face of float is formed with a boss, when level sensor is applied in the thick liquid environment, positioning bar and boss can prevent effectively that the wall of the inner chamber of float and float shell from binding and cause level sensor can't accurately detect level condition.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 is the structural representation of the utility model level sensor.
[embodiment]
With reference to shown in Figure 1, level sensor disclosed in the utility model includes a float shell 10, the lower end of the shell wall 100 of float shell 10 runs through and is formed with a plurality of inlet openings 101, contain a float 12 with cavity 120 in its inner chamber 102, the upper end of the cavity 120 of float 12 is fixed with one first inductor 14, the upper end of float shell 10 is arranged with a containing tube 16,103 places, upper surface that float shell 10 is close in containing tube 16 lower ends are provided with one second inductor, 18, the second inductors, 18 connection output lines 20.
Second sensor 18 is fixed in 103 places, upper surface that float shell 10 is close in containing tube 16 lower ends by a centring ring 22, is convenient to the installation and removal of second sensor 18.
Inner chamber 102 walls of float shell 10 vertically are formed with a plurality of positioning bars 104, it plays the effect of spacing float 12, especially, when level sensor is applied in the thick liquid environment, positioning bar 104 can prevent effectively that the wall of float 12 and the inner chamber 102 of float shell 10 from binding and cause level sensor can't accurately detect level condition.
The end face of float 12 is formed with a boss 121, and it can prevent upper surface 103 bondings of the end face and the float shell 10 of float 12.
Be arranged with a mounting flange 24 on the containing tube 16, it is used for locating the position of level sensor at liquid.
Level sensor places among the liquid, liquid enters float shell 10 via inlet opening 101, its inner liquid level is fair with outside liquid level, and when operating fluid level was in normal range, liquid level floated float 12, first inductor 14 is close to second inductor 18, the equipment operate as normal, when operating fluid level descended, float 12 descended, first inductor 14 is thrown off in second inductor 18 and is surpassed setting value, and equipment produces reports to the police.
Because float 12 is arranged among the float shell 10, comparatively under the situation of upheaval, the inside liquid level of float shell 10 can keep relatively placidity, helps the level sensor level condition of tracer liquid exactly at the outside liquid level of float shell 10.
